The storage and release of energy is an economic cornerstone. In quantum dots (QDs), mostly governed by their surfaces, in particular surface chemistry faceting. impact free (SFE) through faceting has already been studied QDs. Here, we introduce dominant representing the structural order surface. particular, propose that realistic QDs attain complicated polyhedral quasi-spherical shapes while keeping dominance a certain type facet. facet determines rates surface-related processes. Therefore,...
We explain the observed correlation of increased fast emission quantum dots with lower photoluminescence yield as selective lifetime-based quenching, or in other words, preferential switching off slow emission.
